Interface ClipboardOwner

Defines the interface for classes that will provide data to
a clipboard. An instance of this interface becomes the owner
of the contents of a clipboard (clipboard owner) if it is
passed as an argument to
Clipboard.setContents(java.awt.datatransfer.Transferable, java.awt.datatransfer.ClipboardOwner) method of
the clipboard and this method returns successfully.
The instance remains the clipboard owner until another application
or another object within this application asserts ownership
of this clipboard.
